Core Insights - Global warming is exacerbating the occurrence of wildfires, which in turn affects the global carbon cycle, ecosystems, air quality, and human health [2] - A study by Tsinghua University predicts a significant increase in wildfire-related carbon emissions and premature deaths by the end of the century [3][6] Group 1: Wildfire Emissions and Health Impact - The research developed a machine learning framework to predict global wildfire emissions and premature deaths, indicating a 23% increase in carbon emissions from 2010-2014 to 2095-2099 under a moderate emissions scenario (SSP 2-4.5) [3][6] - By 2095-2099, annual premature deaths due to wildfire smoke could reach 1.4 million, nearly six times the current level, with Africa expected to see the highest increase in wildfire-related mortality, projected to rise by 11 times [6][10] Group 2: Long-range PM2.5 Pollution - A separate study quantified the global impact of long-range PM2.5 pollution from the 2023 Canadian wildfires, revealing an increase in global average PM2.5 exposure by 0.17 µg/m³ [10][11] - North America experienced the highest increase in PM2.5 exposure at 1.08 µg/m³, while Europe saw an increase of 0.41 µg/m³ due to long-distance transport [10] - The study estimated that 354 million people in North America and Europe were exposed to PM2.5 pollution from the Canadian wildfires, leading to approximately 5,400 acute premature deaths in North America and 64,300 chronic premature deaths across North America and Europe [10][11]
